Demonic thought is different from others, even without a physical body, its strength still far exceeds that of powerful beings at the same level.
Under the dual power of the Demon Sword and the Life and Death Mirror, it can only seriously injure the demonic thought, but it still can't kill it.
"Luo Yu can only mobilize the full power of the Demon Sword once, if he could use it twice, he might be able to kill the demonic thought."
Unfortunately, this is destined to be just a thought, and it is impossible to achieve it in a short time.
"If I could exchange a divine weapon from the points store and let the Great Princess use it, there might be a chance to kill the demonic thought." Su Nan thought of another method.
Since Luo Yu's strength is not able to increase anymore, increasing the strength of the Great Princess would also be useful.
